LST-1091 was laid down on 3 January 1945 by the American Bridge Co.,
Ambridge, Pa., Iaunched on 3 March 1945; sponsored by Mrs. R. W. Robinson;
and commissioned at New Orleans on 6 April 1945, Lt. Milton S. Johnston,
Jr., USNR, in command.

Following shakedown in St. Andrews Bay Fla., LST-1091 loaded munitions
at Mobile; and, on 11 May, got underway for the Pacific. Early in July,
she embarked Army troops at Saipan, then continued on to Okinawa, arriving
in Buckner Bay on the 28th. There, she disembarked her passengers and, through
the end of the war, distributed ammunition primarily to small craft. Departing
from the Ryukyus on 29 August, she steamed south to the Philippines, offloaded
her remaining cargo; and, in mid-October, headed north to Japan and two
and one half months of occupation duty in the Sasebo area.

With the new year, 1946, LST-1091 got underway to return to the United
States, arriving at San Diego on 29 January. In February, she sailed north
to join the Pacific Reserve Fleet at Bremerton. Inactivation overhaul followed,
and, on 5 July 1946, she was decommissioned and berthed with the Columbia
River Group of the Pacific Reserve Fleet. Named Sagadahoc County
on 1 July 1955, she remained in reserve until transferred to the Republic
of China in October 1958 and renamed Chung Chih. Her name was struck
from the Navy list on 6 February 1959.
